Specification of Letters Patent.

Patentedan. 8, 1918.

To all whom t may concern:

Be it known that I, CHARLES BURNHAM, a citizen of the United States, anda resident of Los Angeles, county of Los Angeles, and State ofCalifornia, have invented certain new and useful Improvements in B0X-Making Machines, of which the following is` a full, clear, and exactdescription.

This invention relates more particularly to machinery for making berryor fruit baskets in which the body is made from veneer shocks and thesaid shocks folded and held together by a metal binding.r

lhere the baskets or boxes are yof a small size the metal binding may beand in the character of machine invented by me and such as disclosed inmy Patent No. 1,119,343, granted December 1,1914, is made from a singlenarrow metal strip which is folded substantially rectangular ac,-cording to the shape of the box or basket and bound thereto, but wherethe boxes are of a large size as for example what are known as ve poundboxes, the machine to handle a single strip would be necessarily largeand its feed slow for handling a strip long enough for such purposes. Itis desirable therefore that in makino' this classv of bones or basketsthat the binding be made of at least two pieces and so manipulated that.they may be simultaneously formed and bound to the box body aseffectively as is done with a single strip for the small sized boxes.

One of the principal objects of the present invention is to provide amachine which is automatic; in action and which is adapted to take twonarrow strips of binding meta-lf,l form them substantially U-shaped incross'- section, and bend the strips transversely about a. former oranvil and clench the binding metal thus formed to the folded box body..

Another object of the invention is to; pro-A vide. simple and eiiicient.means whereby twol metal Strips may be benty about a former fromopposite sidesthereof and.- the: bent .ends of the strip made. tooverlap so as to. form substantially single binding or rim to adapt thesame toA be'applied to a.; box body.

Other objects of the. invention are to pro-- vide. a simple andeliicient press for simu'l.` taneously folding the strips substantial-lyU-shaped lengthwise thereei; to provide simple and efficient meanswhereby two strips may be fed the same or different distances; toprovide simple and eiiicient cutting means for the strips; and toprovide ei'fectivel means for simultaneously folding the strips aboutan. anvil or former.

A. furthe-r object of the invention is to provide simple and eiiicientmeans for holding the bent strips about the anvil or former in positionto permit a box body to be inserted therein and the binding itselfclenched or bound to the box body.

A still further object of the invention is to provide aneffectivemachine for making baskets or boxes which will have a largeoutput and which is adapted to make baskets or boxes of various sizes. l

litli these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawings,which form a part of this specification, and will then be pointed out inthe claims at the end of' the description.

In the general construction of the machine shown in thepresentapplication, the metal binding is fed as two long strips from separatereels or otherwise or as a strip of double widthV which is cutlengthwiseto form two strips. The two strips are fed lengthwise ofthemachine on opposite sides thereof to a press which simultaneously bendsthe two strips lengthwise substantially U-shaped or V-shapedv incross-section. In advance of the press is feeding means for the twostrips which is adapted to force the strips forward a determined lengthand as the strips are fed forward, they are tilted so that one sideassumes substantiaily a verticutting means, the bending means bends the1 two strips toward each other on the sides of a substantiallyrectangular anvil or former corresponding to the shape of the box orbasket to be made, and during such bending, moving two of the ends ofone of the strips downward to permit the ends to pass under the ends ofthe other strip to underlap the same properly, the said strips as thusbent to form a rim being suitably supported on the anvil ready toreceive the body or box-form. During the forming and bending of thebinding, shocks arranged in different magazines are automaticallyremoved' and placed in receivers of a rotary carrier so' as to liecrosswise of each other'. The shoolrs in this crosswise position aremoved between the die and punch of punch ward into the binding or rimwhile still supported on the anvil or former. As soon as the boX body isproperly inserted in the binding or rim, suitable clencher mechanismlocated adjacent. to the anvil and about the punch is made to clench themetal binding about the boX body after which the box body is removed inany suitable way and may be again placed in the carrier and conveyedfrom the machine or automatically ejected therefrom and stacked.

While the invention is shown as employed in connection with a machine ofthe automatic character described, it will 'be understood that many ofthe parts may be used in connection with a hand-operated machine or in amachine of av construction differing from that set forth herein.

The frame 10 of the machine may be of any suitable form and located atany convenient point thereon is a press 11. The press 11 has two narrowstrips or ribbons 12 and 12EL of any suitable material usually tin orgalvanized iron, which may be supported by or fed to the machine. in anyconvenient way, or the said strips may be unwound from spools or reels.rEhe press 11 is adapted to fold the two strips lengthwise thereofsimultaneously substantially U- shaped or V-shaped in cross-section andcomprises essentially two heads 13 and 13a with parts of which cooperatemovable blades or members 14 and 14EL respectively, the latter beingadjustably held by screws 15 or otherwise to a reciprocatory cross-head16. The parts of the press located in the heads 13 and 13a aresubstantially the same and the parts coperating therewith mounted on thecrosshead are likewise similarly constructed. The parts'mounted in theheads 13 and 13 each have a plurality of metal plates 17 and 17a of abar-like form located on opposite sides of a center plate or bar 18which latter is yieldingly held to move vertically. The platesorvmembers 17 17a and 18 as well as the members 14 and 14, aresubstantially identical and operate in the same manner as in my PatentNo. 1,154,970, but as a single press. The cross-head 16 is: suitablyguided toy move vertically in the frame 10 and at theA lower end thereofis connected to arms 19. One end of each arm 19 is pivoted, at 20, to abracket 21 on the frame 10, the other end being provided with a trundleor roll 22 which is adapted to be operated by a cam 23. on the driveshaft 24. Asi the shaft 24 is rotated, they cams 23 will move the arms19 and cross-head 16 causing the members 14 and 14a to be forced upwardso. that both strips will be simultaneously folded lengthwisesubstantially U-shaped or J- shaped in cross-section as set forth in thesaid application.

As a means for feeding the strips to and from thei press, arrange in,advance of said press suitable feeding mechanism 25. This feedingmechanism may be variously constructed. As shown, there is a shaft 26which is held in the outer end of arms 27,` the latter being pivotallyheld, at 28, to brackets 29 forming a part of the frame of the machine.The free ends of the arms 2.7 are normally forced downwardly by springs30, one end of which is secured to the arms and the other end to a partof the brackets 29. On the rod or shaft 26 on opposite sides thereof andadjacent to but over the sides of thel machine frame are grooved wheelsor elements 31 which are adapted to cooperate with rotary elements orwheels 32 having ribs 32al which enter the grooves in the wheels 31 andbetween which wheels 31 and wheels 32 the folded metal strips pass. Thewheels 32 are supported on a shaft 33 arranged in vertical alinementwith the shaft or rod 26. Y rilhe grooved element or wheel 31 and thewheel 32n are held to spur gears 34 and 36, respectively, and rotate inunison therewith on the stationary shaft or rod 26 and 33, said groovedwheel 31 being prevented from moving lengthwise of the shaft 26 bycollars 35. The gears 34 are each in mesh with the spur gears 36, thelatter being secured by screws or otherwise to the ribbed elements orwheels 32. The gears 36 are each held to or formed as a part of onemember 37 of a clutch 38, the member 39 of each of said clutches beingheld to rotate with a pinion 40. Each pinion 40 is adapted to mesh withthe teeth of a vertically reciprocatory rack 41. The racks 41 are eachsuitably guided in the frame or brackets located thereon. At their upperends the racks are angular in form, as at 42, in which are arrangedadjustable stops 43 in the form of bolts or screws which are adapted toengage parts 44 of the brackets 29. rIhe lower ends of the racks 41 arereduced and. arel guided in sockets 45 of a cross-head 46,. the latterbeing guided between the sides of the frame. The racks 41 are normallyforced downward by springs 47, one end of each of which is secured toone of the racks and the other end to a fixed part of the frame, whilethe racks are moved against the tension of the springs 47 during thevertical movement .of the cross-head 46. This crosshead 46. is connectedby one or more links 48 to the outer end of an arm 49.y This arm 49 ispivoted, at 50,. to a bracket on the frame and has a trundle 51 which isadapted to be engaged by a cam on the drive shaft 24, the said arm 49being normally forced downward by means of a. springy 5.3 or otherwise.As the racks 41 are independently adjustable, different distances offeed or the same feed if preferred for the two strips of binding'l metalmay be obtained.v The downward movement of the racks 41 is limited bythe screws or bolts 43 and as the lower ends of the racks are free tomove. in the sockets 45, the cross-head'46 may move of the machineframe.

a certain distance before it operates and moves one of the racks 41 andthen further movement may operate the second rack. It will be noticed inFig. 2 that the vrack at the right hand will be operated a greaterdistance than the one on the left hand because the cross-head or thesocket piece 45 will engage the lower shoulder of the rack on the righthand before the socketvon the left hand engages the shoulder Vof therack on that'side of the machine. 1n this way a very nice adjustment maybe secured whlch may vary in extent and inwhich the feed of thetwo'strips may be the same or the extent of feed of one strip made toexceed that of the other.

Each of the'strips of metal binding is tilted so as to present one sidesubstantially vertical in order that the strips may be bent properlyabout the anvil or vformer and that it may be in position better toreceive thefolded shocks' forming the boX Ybody prior to being clenchedor bound thereto.v

As shown, the framev may support two guide bars V54C and 54a which areheld together by screws 55 or otherwise to form a lengthwise channeledguide for the metal strips on opposite sides of the machine. rllheguides have channels 56 which are adapted to vary in shape lengthwise ofthe guides. As shown in Fig. 31, the guide channels or grooves 56receive the strips in substantially the positionit is formed by thepress. At the section where Fig. 32 is taken and as indicated inFig. 1,the groove may be of a circular form in cross-section, while at thepoint where the section Fig. 33 is taken, the groove is of the form orshape of the folded metal binding with one side substantially vertical.Located between the points where the sections Figs. 31 and 32 are taken,and forming substantially a continuation of the guides and on oppositesides of the machine, are tilting rolls shown best in Figs. 1 and 34. Agrooved roll or member 57 is held to rotate on a stud 58 and this studis held von the outer end of an arm 59, the latter being pivotally heldto a bracket or part A ribbed roll 60 is held to rotate on a stud 61which is held to the machine frame and said ribbed roll is adapted tocooperate with the roll 57. These rolls are angularly arranged withrespect to a vertical plane and the grooved roll 57 is yieldingly forcedtoward the roll 60 by a spring 62, one end of which may be attached tothe machine frame and the other end to a part of the arm 59. The shapeof the rib of theroll 60 and the groove of the roll 57 correspond to theshape in cross-section of the folded binding strips, and during theforward feed of the strips, the latter will be caused to be tilted andthe tilted strips guided through the guide grooves 56,

there being a set of tilting rolls for each of the strips.

Each strip after it has been fed inward the proper distance and tiltedas previously described, is cut transversely theV proper length. InFigs. 5 to 10, I show one form of cutting means which may be employed.rlhere is a cutting device or means for each strip but as they aresubstantially the same in construction, a description of one will answerfor that of the other. A bracketor frame 63 has a base 64 and is locatedforward of the tilting means already described. The frame 63 has itsbase provided withV openings through which the body of bolts 65 areadapted to pass so as to securely hold the frame or bracket 63 to themain machine frame. T he heads of the bolts 65 are movable in slots 66in the machine frame to adaptthe frame or bracket -63 to be movedlengthwise thereof in order that the cutting or shearing means mountedthereon may be Y rocate in the casing 67. This cutter is disklike orcircular in formand has a plurality of grooved cutting portions 69 aboutthe periphery thereof any one of which is adapted to serve as one memberofthe cuttingk means. The cutter G8 is adapted to be rotatably adjustedabout the end 70 of a pin or bolt 71 and said cutter'is normally heldagainst rotary movement by a screw or pin 72, said pin or bolt 71serving also as a set, screw or clamping means for the cutter V68. Atthe rear of the cutter 68 is a socket piece or reforming block 73 havinga groove 74 in the lower edge thereof which is adapted to .form acontinuation of oneV ofthe cutter grooves. This reforming block 73 isconnected to a rod 75, the upper end of which is guided in the end of asleeve or thimble 76 and is provided with lock nuts 7 7 on the outer endthereof. A spring 78 is arranged around each rod and tends normally toforce the reforming block or socket piece 73 downward. A cutter orshearing member 79 is located under the reforming block 73 and isadapted to move toward said reforming block, the said member 79 beingadjusted to cut properly by a screw 7 9a. YThe cutter member 79 is inthe form of a tooth ioo There is a rack member 82 which also engages theteeth of the toothed rod 81 which is opposed to the toothed member 80 sothat on the rotary movement of the toothed member 81, the rack members80 and 82 will be forced in opposite directions. The rack 82 carries thecutter member 68 as well as the socket piece 7 8 so that when the metalbinding is fed between the same and the two members are brought towardeach other through the rotary movement of the toothed rod 81, thecutting edge 88 of the cutter member 79 will be forced past the edge ofthe cutter 68, the. socket piece yielding during this movement, whichwill cause the binding to be severed. At the time that the strip issevered, the end may be reformed by the block or socket piece 78 andmember 79 so that when the strips are bent about the anvil or former thelapped ends will lie substantially flush. As soon as one cutting edge ofthe cutter 68 becomes worn, the screw 71 is releasedV and the screw 72moved out and the said cutter member rotated until the next cuttergroove 69 is in position when the screws are again adjusted to hold thecutter. This may be repeated so long` as any one of the cutter groovesis adapted for use. The toothed rods 81 may be simultaneously rotated inthe same direction by any suitable means. As shown, Figs. 1 and 11, onerod has an arm 84 projecting upward therefrom and the other toothed rodor shaft has an arm 85 projecting downward therefrom. These arms areconnected by a transversely extending rod 86. An arm 87 lprojectsoutward from the arm 84 and said arm 87 is connected to a verticallyreciprocating rod 88 which may be operated by a cam or otherwise so thatat each reciprocation thereof, the arms 84 and 85 will be rocked torotate the toothed rods or shafts 81 and thereby move the cutters so asto sev-er the metal binding strips.

The metal binding` strips before being cut oit are fed into the j aws oftransverse bending mechanisms and are severed while held by saidmechanisms. One strip is fed to the mechanism 89 and the other strip tothe mechanism 90 and these mechanisms are adapted to be movedtransversely of the machine so as to bend the strip partly about aformer or anvil 91 to substantially the shape of the box body and insuch a way that the ends of the bent strips will overlap and form insubstance a single binding for a box body. Except as to several featuresof the lapper jaws of the mechanism 90 to be pointed out later, the twomechanisms 89 and 90 are identical and operate in the same manner and adescription of one except as to such features will answer for the otherand like characters will be used to designate similar parts. Themechanism 89 comprises a `central member 92 to each end of which ispivotally held a bending jaw 98. There are two of such jaws each ofwhich is provided with a grooved bar 94 corresponding in shape tosubstantially onehalf of the metal binding when viewed in cross-sectionand which serves as a guide and holder for the metal binding. This bar94 forms substantially a continuation of a similar bar 95 of the centermember 92 so that the strip is guided by said bars substantiallythroughout its entire length. The member 92 comprises a guide member 96having a dovetailed part 97 in which the two parts of the member 98 areheld. The member 96 carries the bar 95 and to said member is held byrivets or otherwise one part of the member 98, the other part beingyieldingly held to the fixed part so as to be forced toward each otherby a spring 99, Fig. 25, and the ends of the spring 99 are attached tothe lugs 100 and assist in moving the jaws 98 to their open position toreceive the strip. Each part of the member 98 has a lug 100 to which ispivoted one of the jaws 98, the said jaws being provided with recesses101 for proper coperation with the former or anvil 91, as will bepresently described. The jaws 98 are pivotally held, at 102, to arms108. There are two arms 108 and said arms each have a lug 104 which isadapted to form a stop for a projection 105 extending outward from thejaw 98, a spring 106 being provided tending normally to hold :theprojection 105 against the stop 104. The arm 108 is hinged or pivoted,at 107, and is formed integral with a guide arm 108. There are two guidearms 108 and each guide arm has a straight surface 109 which is adaptedto engage a roll 110, the latter being mounted upon an adjustablebracket 111 secured to a part of the machine frame, the said bracketbeing adjustable by means of a bolt 112 or otherwise. The pivot 107extends through a lug or projection 118 of a bracketor support 114.There are two brackets 114 which are secured to the outer ends of a rodor shaft 115. This shaft 115 is mounted in the lower end of projectingarms 116 of a slide frame 117, the latter being guided upon a guide bar118 which is secured at one end to the projecting part 119 of the framebracket 120 and at the other end 121 to a frame bracket 122. The bracket0r slide 117, arms 116. rod 115 and brackets 114 form substantially across-head for the mechanism 89. The slide 117 may be provided withadjustable gibs 128 for taking up any wear that might occur in the slideand the rearward movement of said slide and parts mounted thereon islimited by means of a bolt 124 which passes through and may be locked toa lug on the end'121 of the frame bracket 122. The slide i continue tomove while the member 92 remains stationary and this will cause the jaws93 to be moved on their pivots against the tension of the springs 106about the corners A of the anvil so as to fold the outer ends of thestrip on opposite sides 129 of the anvil, the said folded strip beingheld to the anvil and retained thereon on the return movement of thecross-head and bending jaws.

The grooved bars which initially receive the folded strip are open atone side and when'initially received, the lengthwise folded strip isheld in the groove at this time fia . by a bar or shutter 130 which issupported by two pivotal arms 13011, the latter being held to atransversely extending 4rod 131. This rod 131 is mounted to rotate inbrackets attached'to-the frame bracket 120 and said rod has an arm 132which is adapted to be oscillated by a cam or otherwise operated lever133 so that immediately before the member 92 and jaws 93 are movedforward to a folding position to advance the strip against the anvil,the bar Orshutter 130 is raised.Y The folding jaws are provided withretaining fingers 134 to hold the strip in place after the shutter 130is raised Vand during the folding operation until the folding is nearlycompleted, said lingers being pivoted to lugs 135. These fingers havetheir forward ends 136 extending downwardly and are adapted to hold thestrips in the grooved bars 94 of the jaws during the forward movement ofthe cross-head. The fingers 134 are automatically released just prior tothe last part of the folding operation by the engagement of the ends 137with tixed projecting parts, as cams 137, Fig. 11, so that the jaws cancontinue the remaining short distance to swing the vends of the stripagainst the anvil and in order to leave the strip on the anvil when thejaws are returned to their normal position, the anvil being notched, asat 137), in the sides thereof for the end of the fingers 134 to enter.The fingers 134 are normally pressed to an engaging position by means ofsprings 138 or otherwise. The bar 95 of the center carrier member ofeach of the mechanisms 89 and 90, may be alined during the backwardmovement with the bars 94 of the jaws by engaging with the ends ofadjustable screw stops 138%- Fig. 23, arranged in fixed frame lugs orbrackets 1381.

I have described in detail the action vof the mechanism 89 withoutparticular reference to the Vmechanism 90. This mechanism 90 issubstantially the same construction and operates in a similar manner tothe mechanism 89 and the same reference letters corresponding to likeparts of the two mechanisms are used to indicate like parts, theV maindifference between the two mechanisms being that the jaws of themechanism 90 have a part thereof constructed so that the ends of thestrip carried by the mechanism 90 as it is advanced toward the former oranvil 91 is adapted to be forced downward so as to lap under the ends ofthe other folded strip. These jaws of the mechanism 90 I term the lapperjaws, and the mecha- 95 of the carrier or intermediate member 92. Themember 140 with the bar has a tongue and groove connection, as at 142,with each lapper jaw 139, and said tongue and groove connection inclinesat an angle, as shown best in Fig. 17. The member 140 is pivoted, at143, Fig. 17, so that its outer end will swing downward and is adaptedto carry therewith the outer end of the metal binding so that it may beYforced under and into the ends of the strip bent by the mechanism 89,the strips being somewhat longer than isnecessary to extends'ubstantially midway of the anvil 91 in order to provide overlappingends. The members 140 of the lapper jaws 139 are` normally forced upwardby means of springs 144 arranged around the screws or bolts 145, andsaid members 140 are adapted to be moved downward during the swinging ffolding movement for bending the strip about the anvil by means of cams146, Figs. 20 and 27, of the clenching mechanism in substantially thesame manner as disclosed in my Patent No. 1,154,610.

The mechanism 90 has fingers 134 in the jaws for retaining the metalstrip in the grooved bar 141 as in the mechanism 89 and also has theinitial holding shutter 130 with the supporting arms 130a as'describedin connection with the mechanism 89. The rod 131 of the mechanism 90 hasan arm 147 which projects downward and this arm is connected by a rod148 with an arm 149 which extends upward from the shaft 131 Vof themechanism 89 so that on the reciprocation of the rod 133, the two rods131 on opposite sides of the anvil or former 91 will be operated inunison and in opposite directions to adapt the shutter 130 to be raisedwhen the mechanisms are moved to bend the strips about the anvil orformer, the mechanism 89 being adapted to move slightly in advance ofthe mechanism 90, though the two mechanisms may move simultaneously ifpreferred.

The ends of the metal binding folded about the anvil or former by themechanisms 89 and 90 may be supported and held in any desired way. Asshown, I provide two hooks or latches 150, Figs. 28 and 29, and twoothers 151, shown in Fig. 30, though this number of either or both formsof latches may vary. The latch 150 is of a lixed character and the latch151 of a yielding character, there being two of each, the spring latchor catch being adapted to cooperate to hold the strip bent by themechanism 89, and the latches or catches 150 being adapted to coperateto hold the ends of the metal binding folded by the lapper mechanism 90.The latch 151 is pivotally held, at 152, in a socket piece 153. Thissocket piece 153 is adapted to be inserted in a recess or openingconvenient to the anvil 91 and may be held therein at the outer end bythe end of a plate and may be adjusted outwardly at the rear end bymeans of a screw 154. The hook or latch 151 has a slot or groove 155which is adapted to receive the end 156 of a spring 157, the lattertending normally to force the outer end of the hook or latch downward.'The outer end of the latch 151 has a curved lower surface 158 and a lip159 which is adapted to engage under the lower edge of the substantiallyU-shaped binding strip. As the strip is folded about thefanvil or former91 by the mechanism 89, the ends will engage the curved portion 158 toraise i, the latch on the pivot to permit the strip to pass by and assoon as the strip is against the anvil, the outer end of the latch willbe forced downward by the spring 157 so as to cause the lip 159 of eachlatch to engage the end of the metal binding. As the ends of the stripfolded by the mechanism 90 are forced downward by the jaw members topermit lapping, the latch 150 in such cases does not have to be pivotedbut may be of a fixed character. The latch 150 has its lower endprovided with a lip 160 which is adapted to engage the under edge of oneside of the folded strip and said latch has its body portion 161 held ina socket piece or box 162, the said body 161 being provided with aprojecting lug portion 163 to abut against a shoulder 164- of saidsocket piece. The socket piece 162 fits into a recess adjacent to theanvil or former 91 and may be adjusted outwardly by means ofa screw.165. The

box may be held in its adjusted position by means of a tapered screw 166arranged at one side of the box or socket piece. When the metal bindinghas been clenched about the box form as will be presently described, theclenching operation will compress the metal binding to such an extent aswill release the edges thereof from the engaging lips 159 and 160 of thelatches 150 and 151 respectively, so that the binding or metal rim withthe box form may be removed.

rIhe anvil 91 and certain parts coperating with the folding jaws of themechanisms 89 and 90, is shown in a measure diagrammatic in Fig. 11, andthe construction and arrangement thereof is shown more in detail inFigs. 20 to inclusive. rl`he anvil is also shown rectangular and squarebut it may be oblong or of any other desired form and the mechanism forfolding the rim or binding about the same may be correspondinglychanged. As shown, the anvil 91 has corner pieces 167 which may beintegral with the body or separate therefrom and about which the bindingis formed. The anvil is held to a vertically movable head 168. This head168 may havo a sleeve portion 169 about which is an adjustable tubularand sleeve-like stop 170, the lower end 171 of which is adapted toengage the upper edge or surface 172 of said head when the latter ismoved to its elevated position as will be presently described. The anvilhead 168 is provided with extensions or parts 173 about the same whichserve to prevent the rim or binding from being forced about and off theanvil when the box body is inserted therein, and above the head 168 is acasting or member 17eL at the four corners of which are socket pieces175. 175 are the pins 128 which are held thereto by means of screws 17 7or otherwise. The pins 128 serve to form bearings for the recesses orsockets 101 of each of the folding jaws and serve as a pivot for saidjaws during their swinging movement to bend the binding about the anvil.During the folding operation, the anvil is normally below the clenchermechanism or means which forces the binding about the box body and inthe position shown in Figs. 21 and 22, but as soon as the binding or rimis to be bound or clenched to the box body, the head 168 with the anvilwill be moved upward by a spring, not shown, or otherwise and until thesurface 172 of said head will engage the stop 171 as will be furtherdescribed in connection with the clencher and box-forming mechanism.

TWhile this invention refers more particularly to means whereby thebinding or metal rim is formed and applied to the box body, l have shownin a general way one form of In the socket pieces A mechanism for makingthe box body from shooks of wood veneer or other material.

This part-of the mechanism may be automatic in character taking theshooks automatically from magazines and forming the same into box formand placing the box body in position to have the metal rim or bindingclenched thereto in substantially the manner disclosed in my Patent No.1,154,610, or the said mechanism may be of any suitable kind eitherautomatic or operated by hand. As shown in Figs. 1, 20, 21 and 22, theshooks may be arranged in two magazines 178 and 17 9 from which thevshooks are removed in succession by a pneumatic picker 180. Thispneumatic picker has a rotary and reciprocatory movement and is providedwith a plurality of arms 181 each of which has pneumatic or otherdevices to remove the shooks and to hold them in pairs crosswisc andplace them in this crosswise position in a turret or carrier 182. Theturret, carrier or holder comprises four receivers 183. ceive anintermittent rotary movement and is adapted to take the shooks in acrosswise position and place them between the punch mechanism 184 andthe die mechanism 185. Each receiver may have fixed members or clips 186each of which has an overhanging lip 187 under which the shooks areadapted to be forced when deposited therein by the pneumatic picker ordevice 180 and in such a way that the uppermost shook will not spring orbend far enough'to engage the lower shook, the said shooks being adaptedto be removed by the punch and die mechanism.

The die mechanism comprises a base or l bottom piece 188 and a rubbersuction member 189 which is held to a vertically movable tubular member190 connected to the die head 191. The tubular member 190 is adapted tobe connected to suitable pneumatic suction means to adapt suction to becreated and destroyed therein so that suction may be exerted on thebottom of the box after being completed for the purpose of stripping itfrom the punch 184, the bottom of the plate 188 as well as the tubularscrew 192 for holding the plate in position being slotted or groovedalong the upper surface thereof to permit air to be drawn within thetube or connection 190. Around the bottom or base 188 are four yieldingbottom plates 193 and movable about said bottom plates are four wings194. Each wing 194 has a presser plate or member 195 at the outer endthereof and each wing at its inner end is provided with recesses whichare adapted to be engaged by spring-pressed bolts 196, the spring beinginterposed between the head of said bolt and a lug 197. The wings 194are connected to arms 198 and these arms are connected by links 199 tothe die head and in such a way that during the folding movement of thedie, the

This turret is adapted to re-V wings attheir inner ends will move aboutthe edges of the yielding bottom plates y193 with a lapping effect andin such a way that the shooks at the pointof fold will be held andprevented from breaking or slivering particularly when the shooks aremade of wood. The die mechanism moves bodily upward through one of thereceivers of the turret and meets a presser foot 200 of the punch 184.lThis punch has members 201 and 202, the latter having four yieldingsides 203, the latter being forced outwardly by springs 204 and limitedin such outward movement by screws 205 or in any other suitable way.Above the yielding sides 203 is the anvil or former 91 about which themetal strips have been formed and which metal strips have been bentsubstantially rectangular in form to correspond to the shape of the boxform with the folded edges downward so that during the upward movementof the die with a part of the punch mechanism which has been moveddownward to meet the die to clamp the shooks and which is folded duringthe upward movement of the die and punch mechanism, will receive theupper edges of the box form.

The binding or rim is adapted to be forced or clenched about the boxform by any suitable mechanism. AS shown, levers 206 are pivoted, at207, about the punch and at their upper ends are connected by togglelinks 208 to a movable part or sleeve 209 which is adapted to force thelower ends of said levers 206 toward or away from the anvil. At thelower part of each arm 206 is a clencher jaw 210 which when the anvil ismoved after receiving the box form to a position in alinement with saidgripping jaws, the latter will'be operated so as to clench the bindingor rim securely to the box body. The clenching is done at the lower edgeof he rim of the box body which is necessarily narrow and in such a wayas to force the same into the wood and thus make substantially adovetailed connection with the wood. As the wood is more or less dampwhen the box body is made, it will diminish in thickness when it becomesdry and will have a tendency otherwise to become loose from the metalrim, but by clenching the rim in the manner disclosed so that the loweredges are bound into the wood to squeeze the wood substantiallydovetailed at the upper edge, the wood body cannot become detached fromsaid rim, the latter, during the clenching operation, being releasedfrom the latches or hooks 150 and 151 as already described. During theclenching operation, the anvil is raised by a spring or otherwise untilthe end 171 of the sleeve stop 170 engages the surface 172 of the anvilhead 168. The head 168 and member 202 of the punch are forced downwardand held in this position to place theanvil in alinement with thefolding mechanism by the downward movement of the sleeve 209 engagingthe upper end of the sleeve 169 which forms an extension of t-he anvilhead 168. After the box or basket is formed, suction is created in thetubular member 190 which together with the presser foot 200 will stripthe box from the punch and will deposit the same in substantiallyY-shaped brackets 211 located in the four corners of each receiver 183of the turret or carrier 182,when on further movement of the turret toplace another set of shooks in position to have the box form made, thecompleted box will be carried away out of the path of the punch and diemechanism in a convenient position for ejecting or other means. rlheparts as thus described relating to the means for making the box form,are substantially the same as disclosed in my application hereinbeforereferred to.

The link connection 125 shown in detail in Fig. 24 for operating thecross-head of the folding mechanisms 89 and 90, may be variouslyconstructed. As shown, it comprises essentially two members 212 and 213which are yieldingly held together so that it will be impossible for theparts of the mechanism to be broken if the parts are not adjustedexactly'when the folding jaws and carrier members are moved toward andagainst the anvil. rl`he member 212 has a threaded stem 214 and lockedto .this stem is a sleeve or thimble 215. rlhe stem 214 has an opening216 in which the end 217 of a rod 218 of the member 213 is adapted toslide. On the rod 218 are lock nuts 219 and interposed between the locknuts 219 and the threaded stem 220 of a member 221 is a spring 222. Thesleeve or thimble 215 is held to the threaded stem 220 of the member221, and said member 221 forms a guide for the outer end of the rod 218.The two members 212 and 213 are therefore connected together so as toform a yielding connection between each cross-head of the foldingmechanisms and its operating lever 126.

The operation of the invention will be readily understood from theforegoing description when taken in connection with the accompanyingdrawings. The two metal strips having been fed into the machine ony*opposite sides thereof are advanced forward by the feed mechanism thedesired distance, the said strips having been bent or folded lengthwiseby the press 11. As the strip is advanced forward after being foldedlengthwise, it is tilted by the guides and tilting rolls and suitablyguidedv into the folding and lapper jaws of the folding mechanisms 89and 90. The shutter 90a is raised and the folding jaws with thecross-heads are moved toward the former or anvil 91 fromv opposite sidesthereof and during such folding movement the jaws will pass about the'an1y vil or former, the ends of the strip carried by the lapper jaws 139of the mechanism 90 being forced downward so as to lap under the ends ofthe strip folded by the mechanism 89, the ends of the folded stripsbeing held by the latches 150 and 151 as already explained. The boX formor body during the time that thc folding of the metal binding is takingplace, has been proceeding, and said box form when folded by the punchand die mechanism as already explained, will be fed into the binding andclenched thereto by the jaws 210 of the clenching mechanism.

ln 35 to 39, a construction somewhat different from that shown in theother views and particularly in Fig. 2 is provided for feeding twolengthwise folded strips either the same or different distancespreparatory to the same being cut and bent around the anvil. Thisconstruction is somewhat simpler than thatshown in the other figures andordinarily l prefer to use this construd tion of feed. It differs fromthat shown in Fig. 2 primarily in using a different form of clutch orratchet mechanism and in employing a single rack and pinion instead oftvfo racks and pinions which cooperate with said racks. The groovedmembers, rolls or wheels 223 are rotatably held upon a shaft 224, thelatter being carried by pivotally held arms 225. The arms are normallyforced downward by springs 226, one end of which is held to the arms andthe other ends being held to the machine frame. The springs 226 tend toforce the grooved wheels 223 toward the ribbed wheels, rolls or members227. Each wheel 227 is provided with a gear 228 which is in mesh with asimilar gear 229, the latter being movable with one of the groovedwheels or rolls so that the grooved and ribbed wheels may rotate inunison. Each ribbed roll or wheel 227 is provided with a hub or drumportion 230, the inner part of which is provided with ratchet teeth 231forming an intern al ratchet wheel. The ratchet teeth 231 are adapted tobe engaged by pawls 232 which are pivoted, at 233, to the outer ends ofarms 2311. rl`hc arms 234 for each wheel form a lever which is held to atransversely extending shaft 235 by means of a key 235a or otherwise sothat when the shaft 235 is rotated or oscillated as will be presentlydescribed, the pawls 232 will engage the ratchet teeth 231 of each wheel227 and will rotate the same about the shaft 235. There are two pawlsfor each wheel 227. The pawls are arranged diametrically opposite eachother and each pawl' is normally forced to an engaging position by meansof a spring 235b one end of which is seated in a recess in the pawl andthe other end lin a recess in the pawlcarrying arm 234.

g The ribbed wheels 227 are loosely mounted ELO upon the shaft 235 andareheld against lengthwise movement on said shaft. A. pinion 236 is heldto the shaft substantially midway between the gears 228 and adapted toengage said pinion is a toothed rack '237. This rack is adapted to movevertically and may be reciprocated by any suitable means such forexample as links 233. As the rack 237 is reciprocated, it rotates thepinion 23 and this will rock the shaft 235and move the pawl-carryingarms 234. rlhis will cause a rotary movement to be given tothe ribbedwheels 227, which, owing to the intermeshing gears 228 and 229, willimpart a like rotary movement to the grooved wheels 223.

As a means for regulating the extent of movement of the feed rolls, thepawls 232 may have their engagement with the teeth 231 regulated. T hismay be secured in various ways. As shown, a lever oi element 239 foreach set of pawls is loosely mounted upon the shaft 235 and cach outerend of said lever carries a cam portion 240 upon \\'hirh tlie pawls 2"2may ride for a part of their movement. Each lever 239 has a slottedextension 2ll through which passes a pin or bolt 2112. The bolt 24:2extends through a lug 243 on a. part of the machine frame so that bymeans of said bolt, the position of the lever 239 and the cams 240 maybe changed relatively to the normal poH sitien of the pawls 232. Bymoving the cams 240 away from the pawls, the latter will engage agreater numb Ar of teeth and'eonsequently a greater throw or movementwill be imparted to the feed rolls, and the reverse takes place when thecams are moved toward the pawls, for in that ease the pawls in theirmovement in one direction will be disengaged sooner from the teeth 231,and the means for disengaging the pawl by the cam 240 being more clearlyshown in Fig. 38.

By shifting the cams 240 on one side of the machine differently from thecams on the other side of the machine, the feedV rolls or wheels will bemoved diierent distances and different extents of feed will be obtainedfor the binding metal, while by having the cams on both sides of themachine similarly adjusted with respect to the pawls 232, the sameextent of feed of the metal binding is obtained.

From the foregoing, it will be evident that folding and bending thestrips and for holdf ing the same about an anvil or former; that simplefeeding and cutting mechanism is provided whereby the strips may be fedthe .shown and described as adapted particularly for machines whereinthe entire basket is made automatically, the said mechanism or partsthereof may be of such a character that they may be employed in Yvariousconnections and for making boxes of various sizes.
